NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and Space Environment Research Center, Japan.


Quiet to unsettled conditions.

2. FORECAST (14 AUGUST - 13 SEPTEMBER)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 18 Aug to 20 Aug,  5 Sep to 6 Sep

Best Quiet Periods: 
 14 Aug to 17 Aug,  21 Aug to 4 Sep,  7 Sep to 13 Sep.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 14 Aug to 16 Aug,  20 Aug to 2 Sep,   7 Sep.

Pc3 pulsations are high frequency (10-45 second period) variations 
of the Earths magnetic field. Daily pc3-indices are the daily sum of 
20 minute pc3-indices for that station and have been shown to be well 
correlated with rejection of high resolution aeromagnetic survey 
flight-line data.

PLEASE NOTE:
Geomagnetic activity can frequently be determined by short timescale 
solar events that cannot be forecast a week in advance, particularly
at solar maximum.
